We are superseding airworthiness directive (AD) 2014-12-51 for Airbus Helicopters (previously Eurocopter France) Model EC130B4 and EC130T2 helicopters. AD 2014-12-51 required repetitively inspecting the tailboom to Fenestron junction frame (junction frame) for a crack. This new AD retains the requirements of AD 2014-12-51, changes the applicability from helicopters with certain hours time-in-service (TIS) to junction frames with certain hours TIS, and adds a compliance time for sling cycles to the junction frame inspection interval. The actions of this AD are intended to detect a crack and to prevent failure of the junction frame, which could result in loss of the Fenestron and subsequent loss of control of the helicopter.

SUPPLEMENTARY INFORMATION: 

Discussion

    On September 25, 2015, at 80 FR 57742, the Federal Register 
published our notice of proposed rulemaking (NPRM) to amend 14 CFR part 
39 to remove AD 2014-12-51, Amendment 39-17921 (79 FR 45335, August 5, 
2014), and add a new AD. AD 2014-12-51 applied to Airbus Helicopters 
Model EC130B4 and EC130T2 helicopters with 690 or more hours TIS and 
required, within 10 hours TIS, dye-penetrant inspecting certain areas 
of the junction frame for a crack. AD 2014-12-51 also required, at 
intervals not exceeding 25 hours TIS, either repeating the dye-
penetrant inspection or performing a borescope inspection of certain 
areas of the junction frame for a crack. If there was a crack, AD 2014-
12-51 required replacing the junction frame. AD 2014-12-51 was prompted 
by two incidents of crack propagation through the junction frame that 
initiated in the lower right-hand side between the web and the flange 
where the lower spar of the tailboom is joined. The cracks were 
significant in length and not visible from the outside of the 
helicopter.
    The NPRM was prompted by AD No. 2015-0033-E dated February 24, 2015 
(AD 2015-0033-E), issued by EASA, which is the Technical Agent for the 
Member States of the European Union, to correct an unsafe condition on 
Airbus Helicopters EC130B4 and EC130T2 helicopters. The NPRM proposed 
to require retaining the dye penetrant and borescope inspections in AD 
2014-12-51 but with revised compliance times. The NRPM also proposed to 
change the applicability to helicopters with 690 hours TIS accumulated 
on the junction frame instead of on the helicopter, and proposed 
including an inspection interval defined in sling cycles. These actions 
were intended to detect a crack and to prevent failure of the junction 
frame, which could result in loss of the Fenestron and subsequent loss 
of control of the helicopter.

Comments

    After our NPRM (80 FR 57742, September 25, 2015) was published, we 
received a comment from one commenter.

Request

    One commenter requested the addition of a 10-hour or 250-sling 
cycle visual pilot check for helicopters with Modification 350A087421 
or that have complied with Airbus Helicopters Service Bulletin No. 
EC130-53-029, Revision 0, dated February 20, 2015 (SB EC130-53-029). 
The commenter stated this pilot check would benefit operators and 
provide the same level of safety.
    We disagree. While the EASA AD allows the check requested by the 
commenter as an alternative method, because the cause of the fatigue 
cracking is still under investigation, we cannot determine that this 
method would correct the unsafe condition.

FAA's Determination

    These helicopters have been approved by the aviation authority of 
France and are approved for operation in the United States. Pursuant to 
our bilateral agreement with France, EASA, its technical 
representative, has notified us of the unsafe condition described in 
the EASA AD. We are issuing this AD because we evaluated all 
information provided by EASA, reviewed the relevant information, 
considered the comment received, and determined the unsafe condition 
exists and is likely to exist or develop on other helicopters of the 
same type designs and that air safety and the public interest require 
adopting the AD requirements as proposed.

Interim Action

    We consider this AD to be an interim action. If final action is 
later identified, we might consider further rulemaking then.

Differences Between This AD and the EASA AD

    The EASA AD includes alternate compliance instructions for 
helicopters modified with a cut-out in production by Airbus Helicopters 
Modification 350A087421 or in service by compliance with SB EC130-53-
029. This AD does not.

Related Service Information Under 1 CFR Part 51

    We reviewed Airbus Helicopters Emergency Alert Service Bulletin No. 
05A017, Revision 2, dated February 20, 2015 (EASB 05A017), for Model 
EC130B4 and EC130T2 helicopters. EASB 05A017 describes alternate 
procedures for inspecting outside the tailboom for a crack at reduced 
inspection intervals in combination with the internal inspections at 
extended intervals. EASB 05A017 also specifies adding sling cycles to 
the existing flight hour inspection interval for helicopters that 
perform external load-carrying operations. EASA issued AD No. 2015-
0033-E mandating the requirements in EASB 05A017 to ensure the 
continued airworthiness of these helicopters.
    This service information is reasonably available because the 
interested parties have access to it through their normal

[[Page 26105]]

course of business or by the means identified in the ADDRESSES section.

Other Related Service Information

    Airbus Helicopters also issued SB EC130-53-029, which contains 
procedures to cut out the skin and splice at the junction frame to 
facilitate the external inspection specified in EASB 05A017.

Costs of Compliance

    We estimate that this AD affects 208 helicopters of U.S. Registry. 
We estimate that operators may incur the following costs in order to 
comply with this AD. At an average labor rate of $85 per work-hour, 
dye-penetrant inspecting the junction frame will require 1 work-hour, 
for a cost of $85 per helicopter and a total cost of $17,680 for the 
U.S. fleet, per inspection cycle. Borescope inspecting the junction 
frame will require 0.5 work-hour, for a cost of $43 per helicopter and 
a total cost of $8,944 for the U.S. fleet, per inspection cycle.

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue rules on aviation safety. Subtitle I, section 106, describes the 
authority of the FAA Administrator. Subtitle VII: Aviation Programs, 
describes in more detail the scope of the Agency's authority.
    We are issuing this rulemaking under the authority described in 
Subtitle VII, Part A, Subpart III, Section 44701: ``General 
requirements.'' Under that section, Congress charges the FAA with 
promoting safe flight of civil aircraft in air commerce by prescribing 
regulations for practices, methods, and procedures the Administrator 
finds necessary for safety in air commerce. This regulation is within 
the scope of that authority because it addresses an unsafe condition 
that is likely to exist or develop on helicopters identified in this 
rulemaking action.

Regulatory Findings

    This AD will not have federalism implications under Executive Order 
13132. This AD will not have a substantial direct effect on the States, 
on the relationship between the national government and the States, or 
on the distribution of power and responsibilities among the various 
levels of government.
    For the reasons discussed above, I certify that this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866;
    (2) Is not a ``significant rule'' under DOT Regulatory Policies and 
Procedures (44 FR 11034, February 26, 1979);
    (3) Will not affect intrastate aviation in Alaska to the extent 
that it justifies making a regulatory distinction; and
    (4) Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.
    We prepared an economic evaluation of the estimated costs to comply 
with this AD and placed it in the AD docket.

1. The authority citation for part 39 continues to read as follows:

    Authority:  49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by removing Airworthiness Directive (AD) 
2014-12-51, Amendment 39-17921 (79 FR 45335, August 5, 2014), and 
adding the following new AD:

2016-08-20 Airbus Helicopters (Previously Eurocopter France): 
Amendment 39-18497; Docket No. FAA-2015-3970; Directorate Identifier 
2015-SW-006-AD.

(a) Applicability

    This AD applies to Airbus Helicopters Model EC130B4 and EC130T2 
helicopters with a tailboom to fenestron junction frame (junction 
frame) that has 690 or more hours time-in-service (TIS), 
certificated in any category.

(b) Unsafe Condition

    This AD defines the unsafe condition as a crack in the junction 
frame. This condition could result in failure of the junction frame, 
which could result in loss of the Fenestron and subsequent loss of 
control of the helicopter.

(c) Affected ADs

    This AD supersedes AD 2014-12-51, Amendment 39-17921 (79 FR 
45335, August 5, 2014).

(d) Effective Date

    This AD becomes effective June 6, 2016.

(e) Compliance

    You are responsible for performing each action required by this 
AD within the specified compliance time unless it has already been 
accomplished prior to that time.

(f) Required Actions

    (1) Before the junction frame reaches 700 hours TIS or within 10 
hours TIS, whichever occurs later, remove the horizontal stabilizer, 
clean the junction frame, and dye-penetrant inspect around the 
circumference of the junction frame for a crack in the areas shown 
in Figure 1 of Airbus Helicopters EC130 Emergency Alert Service 
Bulletin No. 05A017, Revision 2, dated February 20, 2015 (EASB 
05A017). Pay particular attention to the area around the 4 spars 
(item b) of Figure 1 of EASB 05A017. An example of a crack is shown 
in Figure 3 of EASB 05A017.
    (2) Within 25 hours TIS or 390 sling cycles, whichever occurs 
first after the inspection required by paragraph (f)(1) of this AD, 
and thereafter at intervals not exceeding 25 hours TIS or 390 sling 
cycles, whichever occurs first, either perform the actions of 
paragraph (f)(1) of this AD or, if the area is clean, using a 
borescope, inspect around the circumference of the junction frame 
for a crack in the areas shown in Figure 2 of EASB 05A017. Pay 
particular attention to the area around the 4 spars (item b) of 
Figure 2 of EASB 05A017. An example of a crack is shown in Figure 3 
of EASB 05A017. For purposes of this AD, a sling cycle is defined as 
one landing with or without stopping the rotor or one external load-
carrying operation; an external load-carrying operation occurs each 
time a helicopter picks up an external load and drops it off.
    (3) If there is a crack, before further flight, replace the 
junction frame.

(g) Special Flight Permits

    Special flight permits are prohibited.

(h) Alternative Methods of Compliance (AMOCs)
